The invention discloses an escalator operation condition intelligent monitoring method and system, and the method comprises the following steps: collecting multi-source data of an escalator, including people flow data and equipment state data; preprocessing the collected data, wherein the preprocessing comprises data cleaning and data normalization; constructing an escalator danger early warning network EHPNet based on a Transform network and a graph neural network, and training the escalator danger early warning network EHPNet; and inputting the preprocessed multi-source data of the escalator into the trained escalator danger early warning network, and monitoring the operation condition of the escalator. According to the method, the operation condition is monitored by fusing the passenger flow data and the equipment state data of the escalator, comprehensive and real-time monitoring and deep insight of the passenger flow, the safe operation state and the equipment health state are achieved, and potential safety hazards can be found in time to guarantee elevator taking safety.

The application relates to the technical field of workshop early warning management, and specifically discloses a vaccination workshop environment microorganism concentration intelligent early warning system, which realizes real-time collection of environment parameter data of a vaccination workshop through an environment sensor network, extracts microorganism concentration key driving factors, and obtains key driving factor data; a causal network for microorganism concentration prediction is constructed based on the key driving factor data, and a causal network model is obtained; the environment parameter data set is subjected to microorganism concentration growth slope calculation according to the causal network model, then a regulation and intervention strategy is generated based on a counterfactual reasoning algorithm and intervention effect simulation is carried out, so that an optimal regulation and control scheme is output; the intelligent level and response precision of microorganism pollution prevention and control are greatly improved, the adaptability of the system to a complex dynamic environment is enhanced, energy waste or system disturbance caused by excessive intervention is avoided, and the workshop automation management level is improved.

The application discloses a controllable cold energy releaser and a cold storage system, and belongs to the technical field of cold storage energy saving. The controllable cold energy releaser comprises a refrigeration mechanism, a container, a cold storage medium, air ducts and a cold energy release control mechanism. The container is internally provided with the cold storage medium. The container is open at both ends and is integrally provided with heat preservation blocks at the openings. The air ducts are arrayed in the container. The air ducts are penetrated through the heat preservation blocks on both sides and are connected with the cold energy release control mechanism. The refrigeration mechanism is connected with the container and is used for refrigerating the cold storage medium. The outer wall of the container is provided with a heat preservation material layer. The heat preservation material layer is used for blocking the cold energy exchange between the cold storage medium and the outside. The controllable cold energy releaser can realize the controllable release of the cold energy of the cold storage medium, so that the energy saving and consumption reducing effect is further improved, and the automatic management level is improved.
